Matthew 12:34

12:34 Offspring of vipers! How are you able to say anything good, since you are evil? For the mouth speaks from what fills the heart.

Matthew 7:11

7:11 If you then, although you are evil, ¹  know how to give good gifts to your children, how much more will your Father in heaven give good gifts ²  to those who ask him!

[7:11]  ¹ tn The participle ὄντες (ontes) has been translated concessively.

[7:11]  ² sn The provision of the good gifts is probably a reference to the wisdom and guidance supplied in response to repeated requests. The teaching as a whole stresses not that we get everything we want, but that God gives the good that we need.
